Toa/.ZZ whom t .may concern:

Beit known that I, NICHOLAS J. .GoNDoLF, acitizen'of the United States,anda resident of New Orleans, in the parish of Orleans and VSvtate ofLouisiana, have invented certain new and luseful Improvements inFlushing Devices, of which the followinglis a specification.

My present invention relates principally to aflushing vdevice in whichthe :loat is depressed to start the siphon, and in practice, thefeatures relating to the float and-inlet valve are associated with a jetstarter tube and with an after lill tube.

My invention relates particularly in novel means to actuatethe floatcarryingstructure and of other novel means associated withv the rstmentioned means to actuate the siphonstarter jet and the afterll; alsoto means to retain the ioat in depressed position and to prevent thefloat rebounding, Ithe continued lowering ofthe float'due -to theemptying` of the tank serving to release floaty fromthe retainer leavingthe'float free to rise as the tank again lls.

ln the drawings- Figure 1 is a partial side view withV parts brokenaway,

Fig. 2 is a top planview,

Fig. 3 is a-view similar to Fig. 1 showing` the movable parts innormalposition,

Fig. a is a section ,on line -t-of Fig. 3,

Fig. 5 is a detail section on line 5-5 of' Fig. 2,;

Fig. 6 is a detail section on line 6 6 of My invention is applicable toany conven-` tional tank lO of thehigh tank or low tank typeVthoughlfhave shown it in this instance applied to a llow tank, thistanl: has the usualsiphon 11 flared at thelower end and connectedwith-the discharge 12 and an; inlet pipe 13. A ball float-1i is adapted-to be depressed-for f starting, displacing a portion Yof thewater andastartingj et tube 15 adapted for entering the short leggof the siphonand to be moved outzofv the same, the tank receiving a supply of waterfrom the inlet 13..

Arock: shaft 16 is mounted in the tankand.:

operated by a handle16a-said shaft havinga rocking member which.consists of a` ypaircof spaced'apart arms 17, 17svt rigid-ly secured`theretoat one end, the oppositeendscon.-

vergingand connected by a bolt 18 which -is Y mountedtoslide in slot. l9inzl thevlever 20,

said slot. gradually widening in its upper portion and terminating in alateral curve or bend 21 being closed at this end so that the bpltcannot jumpout of the slot and become disconnected from vthe lever. 22.at one end is. screwed into an internally threaded nipple 23 projectingfrom the lever 2O and at its opposite end to the tioat 14.

Water is suppliedto Vthe. tank through the inlet pipey 13which has acontracted bore.

13a andthe valve seat 13b; this ,inlet pipe may be integral with orsuitably secured to the valve casingin which works a piston or plungerinlet valve 25 whichfhas a washer 25a. fitted in its lower end so as totightly fit against the seat 13b; the valve also has ay half itscircumferenceV as shown at 15f inv Fig. 6, `the purposeof which willlater appear. rllhe pipe 2 6 has a lateral port 26?L to. which Va smallpipe 80 is secured, said pipeextending upwardly and discharging into thesiphon 11 as will bev hereinafter more= fully described, saidv pipehaving a set screw plug-valve 30B' to control same. |The starting Jet 15has a weighted lug 151l projecting from oneside which is flexiblyconnected tor one end of rod 32 which vextending upwardly is connectedto. one armv f7@ by means of a slot. 17b therein the upper end of rod 32being secured by the bolt 33 passed through the slot 17" from. theinside throughV the rod and held by a lock, nut 34, the headk 0f thebolt being countersunk in the slot 17,1,

so that lever 20 will have unobstructed play. between the two arms 17and 17%; the starting jet tube -15 also has a. set screw plug valve` 15cto control the How through thetube 30.

The valve casing24 has the rigid bracketarm 24a on onev side and asimilarthough shorter arm 241 on the opposite side; the leverv 20 has abell crank arm; 20"@A which .is pivoted to bracket mm2/sta. and to thefree end of 20l is pivoted the lever 201 flexibly connected to leverz20,which'passes through.`

the upper endk offplunger -25 and is' then y The .lioat rod,v

' the valve casing, the cut-out portion uncoveringrthe lateral port 26fLin pipe 26 when rotated in one direction andthe integral or4 blankportion covering said port when the Jet starter 1s rotated 1n anopposite direction` and these rotations arel caused by the rod 32connected at one end to the jet starter by Vlug 15c and at its oppositeend to arm 17a of the rocking means.

The lower end of the short leg of the siphon is flared sufficientlythat'when the jet starter .tubeY is turned to one side its outlet willbe entirely within the circumference of the flare. j

W ith the parts in the position shown in Fig. 3 the tank being full, itit is desired to flush, the handle 16a is depressed; this causes thearms 17 and 17nl to move upwardly toward the right, the bolt 18 ridingup the slot'19 of the lever 2() and finally rests in the eXtreme end ofthe curved slot 21 and locks the parts, the plunger valve 25 havinglbeen raised by the movements of lever 2() and the starterrjet tube beingswung up to the position shown in Fig. 1 with its outer end projectingupwardly into the Siphon leg; the jet starter having been swung orrotated through the lug v15b and the rod 32 the upper end of which iscarried by the bolt which slides in the slot in arm 17a; the

jetting into the siphon causes the water to 1 be rapidly discharged Vtothe bowl and this keeps up until water falls below theY lower end of theshort leg of siphon which breaks the siphonic action; the parts up tothis point have been held in position by the water pressure on thefloat, but as soon as water tails below the fioat it drops byits weightand this pulls lever 20 and causes the bolt 18 which connects' the arms17 and 17a to lfall back into slot 19, and this .lowers arm 32 which isconnected to lug` 15b on the starting tube 15 causing it, the lug, toswing downwardly and. thus turn the starting tube through 90v degreesuncovering the port 26a and permitting water to flow through after fillpipe 30 to the upper part of the siphon; this action is caused by theplug valve'15c which partially obstructs the bore 15 and. causes vbackpressure through the port 263. As the tank refills the iioat risingswings lever 20 toward its normal osition, the supply water feedingthrough the jet tube 15 which as stated has been swung so that thecurved end is turned out of the siphon leg. The after fill continuesuntil the rising Vwater through the float forces the parts intopositionshown in Fig.

3 when the plunger valve 25 is held to its seat shutting off the inlet;the device is then again ready for use to flush."

r1`he swinging movement of the jet starter 15v is aided by the weight oflug 15b which `is connetted` to the rod 32, and to prevent the tubebeing entirely rotated and the lug 15D being thrown over beyond centerwhen the rod 32 pulls upwardly, a stop device is applied to the tube'15, which in its'p'referred ferm consists of projecting boss or finger151 which' 'will come Ain contact with bottom of the tank as indicatedin Fig. 6; this it will be noted will prevent overthrow Vof the jetstarter tube.VV The eXtra weight of the lug visV secured by they swellor enlarge ment 15e.
